Downloading Twitterrific (Mac & iOS)

Is Twitterrific free or paid?

iOS

Twitterrific for iOS is currently a paid-only application in the
iOS App Store.

Mac

Twitterrific for Mac is completely free when you download it
from the Twitterrific website
to use with a single Twitter account. The application displays an
advertisement from The Deck at the top of the timeline that
highlights products and services you might be interested in. If you
find the ads distracting or otherwise objectionable, you can
purchase a license for Twitterrific that removes them. Purchasing
also enables multiple accounts/windows.

Users who purchase Twitterrific for Mac from the Mac App Store
already own these features and do not need to purchase a
license.
